What is the most important information I should know about thalidomide?

Never use this medicine if you are pregnant. Even one dose of thalidomide can cause severe, life-threatening birth defects or death of a baby if the mother or the father is taking this medicine at the time of conception or during pregnancy.

Use birth control to prevent pregnancy, whether you are a man or a woman. For women: Use two forms of birth control beginning 4 weeks before you start taking thalidomide and ending 4 weeks after you stop taking it. For men: Use a condom to prevent pregnancy during your treatment, and for up to 4 weeks after your treatment ends.

Thalidomide may cause blood clots. Stop using this medicine and call your doctor at once if you have symptoms such as sudden numbness, severe headache, problems with vision or speech, chest pain, shortness of breath, or swelling in your arm or leg.

What is thalidomide?

Thalidomide is used together with dexamethasone to treat multiple myeloma (bone marrow cancer). Thalidomide is also used to treat and prevent moderate to severe skin lesions caused by leprosy.

Thalidomide is available only from a certified pharmacy under a special program called Thalomid REMS. You must be registered in the program and agree to use birth control as required. You will be limited to a 28-day supply of thalidomide each time your prescription is refilled.

Thalidomide may also be used for purposes not listed in this medication guide.

What should I discuss with my healthcare provider before taking thalidomide?

You should not use thalidomide if you are allergic to it.

Thalidomide can cause severe, life-threatening birth defects or death of a baby if the mother or the father is taking this medicine at the time of conception or during pregnancy. Even one dose of thalidomide can cause major birth defects of the baby's arms and legs, bones, ears, eyes, face, and heart. Never use thalidomide if you are pregnant. Tell your doctor right away if your period is late while taking thalidomide.

For Women: If you have not had a hysterectomy, you will be required to use two reliable forms of birth control beginning 4 weeks before you start taking thalidomide and ending 4 weeks after you stop taking it. Even women with fertility problems are required to use birth control while taking this medicine. You must also have a negative pregnancy test at 10 to 14 days before treatment and again at 24 hours before. While you are taking thalidomide, you will have a pregnancy test every 2 to 4 weeks.

The birth control method you use must be proven highly effective, such as birth control pills, an intrauterine device (IUD), a tubal ligation, or a sexual partner's vasectomy. The extra form of birth control you use must be a barrier method such as a latex condom, a diaphragm, or a cervical cap.

Stop using thalidomide and call your doctor at once if you quit using birth control, if your period is late, or if you think you might be pregnant. Not having sexual intercourse (abstinence) is the most effective method of preventing pregnancy.

For Men: If a man fathers a baby while using thalidomide, the baby may have birth defects. Use a condom to prevent pregnancy during your treatment, and for up to 4 weeks after your treatment ends. You must agree in writing to always use latex condoms when having sex with a woman who is able to get pregnant, even if you have had a vasectomy. Contact your doctor if you have had unprotected sex, even once, or if you think your female sexual partner may be pregnant.

Treatment with thalidomide may increase your risk of a blood clot or stroke during treatment for multiple myeloma. Ask your doctor about your specific risk.

To make sure thalidomide is safe for you, tell your doctor if you have ever had:

heart disease, a stroke, or a blood clot;
